you need to run fsck on the drive when it is unmounted.... your picture shows fsck wont run and is sigterming, maybe your missing sys-fs/e2fsprogs on your system? maybe its broken and needs recompilation.

It might help to know what type of file system it is, ie ext4, jfs, etc. and what it is (I assume /, but please confirm/correct)

I beleive /proc already being mounted is suspicious. What type of initramfs are you using? If it is a custom one, did you remember to unmount /dev /proc and /sys?

More pressing is that before you do anything else, backup the data on that disk. Use a live cd, usb drives, magnetic tape, whatever. In this case you may loose the entire drive trying to repair it. As this is in the "installing Gentoo" forum, I guess that is not really an issue.

Judging from the boot up messages, you are trying to run SELinux? What type of kernel? If you do post your .config, please use a pastbin site as long config files clutter the forum.

Please, post more information. I must say from what I am seeing I would guess a failing hard drive, but I would not be too sure._________________First things first, but not necessarily in that order.

OK, so your problem is not a typo. Next on the list, I think a look at the output of dmesg may be revealing. I recommend installing wgetpaste. You may need to emerge it. You can use it by using dmesg | wgetpaste and posting the url returned. This should give us a look at your boot up process so we can see what is going wrong._________________First things first, but not necessarily in that order.
